Title: Dielectric film
Inventor: ANDO MASAKI
IPC: G02B1/115
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To obtain dielectric films which obviate the occurrence of a change with lapse of time by the lowering of a refractive index and the infiltration of water by making a film forming material incident on film forming surfaces obliquely to the normals of these surfaces to deposit the material thereon and subjecting the material to an annealing treatment. SOLUTION: The normals Va, Vb of the film forming surfaces 2a, 2b of an optical element 1 vary in the directions from each other. The material for vapor deposition contg. metallic molecules fly from a vapor deposition source in the direction of an arrow A. The incident angles to the film forming surfaces are nearly equal. The thin films formed on the film forming surfaces 2a, 2b are partly or fully formed of the metal. The metallic films grow obliquely to the film forming surfaces 2a, 2b and since nucle-growth occurs, the metallic films grow at the higher density than in the case the films grow perpendicularly. The metallic films are subjected to a post treatment, such as plasma treatment or thermal annealing treatment to oxidize the metallic molecules and to form the dielectric films.  The formation of the dielectric films by one time treatment on the >=2 film forming surfaces varying in the normal directions is thus made possible.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To obtain a signal processor without dispersion in a frequency characteristic of an amplifier or the like due to a capacitance change by providing a signal processing means processing an input signal and a substrate capacitance detection means controlling the frequency characteristic of the signal processing means in response to a detected capacitance.

When the frequency characteristic of the amplifier 5 is changed due to the effect of the substrate capacitance, a variable equalizer 6 receives the control voltage Vc to correct a change in the frequency characteristic thereby obtaining the frequency characteristic suitable for the processing of a post-stage signal processing circuit 7. Thus, the signal processor without dispersion in the amplifier frequency characteristic due to a capacitance change is obtained.

Abstract: PURPOSE: To prevent generation of black smoke, by shaping the lower surface of the cylinder head in a downwardly projected conical form around the axis of a cylinder, and shaping the upper surface of a piston in a recessed conical form conforming to the downwardly projected conical surface of the cylinder head, so as to obtain a strong squish of air in the cylinder.  
     CONSTITUTION: When a piston 3 formed with a combustion chamber 4 in its top surface comes to the end position (shown by two-dot chain line in the drawing) of compression stroke, squish air enters into the combustion chamber 4 as shown by arrows A. Here, since the upper surface 31 of the piston is shaped in a recessed conical form around the cylinder axis Y and the lower surface 11 of the cylinder head is also shaped in a downwardly projected conical form having the samd cone angle, squish air is made to flow toward the center of the cylinder more strongly as compared with the conventional arrangement and also to collide against swirl formed in the combustion chamber 4. Therefore, it is enabled to promote agitation in combustion chamber 4 and hence to combust mixture efficiently.
